Science Stuff

Writing is not my full time job. In my main job, I am a scientist at the NASAJohn Glenn Research Center, where I work on Mars missions and on developing advanced concepts and technology for future space missions. Click here for the page for my activities in science and technology

Poetry

OK, I admit it: I also sometimes commit acts of poetry, and have even published a poetry collection, Iron Angels. Click here for more about my secret life as a poet.
